La Barra Swell Statistics, Autumn: Surf with Light or Offshore Winds

The rose diagram shows only the swells directed at La Barra that coincided with light winds or offshore conditions over a normal northern hemisphere autumn and is based upon 8476 predictions, one every 3 hours. The direction of the spokes show where quality surf generating swell comes from. Five colours show increasing wave sizes. The smallest swells, less than 0.5m (1.5 feet), high are coloured blue. Green and yellow show increasing swell sizes and red represents the largest swells, greater than >3m (>10ft). In both graphs, the area of any colour is proportional to how commonly that size swell occurs.

The diagram implies that the dominant swell direction, shown by the largest spokes, was NW, whereas the the most common wind blows from the NNE. The chart at the bottom shows the same thing but without direction information. For example, swells larger than 1.5 feet (0.5m) coincided with good wind conditions 16% of the time, equivalent to 15 days. Open sea swells exceeding >3m (>10ft) are unlikely to happen in a normal northern hemisphere autumn but 6% of the time you can expect swell in the range 1.3-2m (4-6.5ft) 6%, equivalent to (5 days). Taking into account the proportion of these swells that coincided with predicted offshore winds, and given the fact that La Barra is exposed to open water swells, we calculate that clean surf can be found at La Barra about 16% of the time and that surf is messed up by onshore wind 52% of the time. This is means that we expect 62 days with waves in a typical northern hemisphere autumn, of which 15 days should be clean enough to surf.

IMPORTANT: Beta version feature! Swell heights are open water values from NWW3. There is no attempt to model near-shore effects. Coastal wave heights will generally be less, especially if the break does not have unobstructed exposure to the open ocean.
